You can't remap arrow keys, WASD and L. Both arrows and WASD are locked to movement, and L is locked to dodge. Furthermore, there's no even the option to rebind movement keys. This makes me unable to configure the controls in any plausible way.
Talk:Blasphemous
If this is the case, the remappable field should be set to "limited" and the notes should mention the controls that cannot be remapped. See the editing guide for details: https://pcgamingwiki.com/wiki/PCGamingWiki:Editing_guide/Input_settings
Controls became remappable after December 17th patch: https://steamcommunity.com/games/774361/announcements/detail/3151888293028716435
